Universal Beams (UB), also known as rolled steel joists (RSJ in older terminology), are structural steel beams with a wide flange and high load-bearing capacity.

They are designed primarily for horizontal load support, making them ideal for:

• Floor beams
• Roof beams
• Warehouse frames
• Mezzanine structures
• Commercial buildings
• Industrial projects

Universal Beams are known for their excellent bending resistance, structural efficiency, and durability, making them one of the most widely used steel sections in construction.
